Subject:	ETX 90 RA secondary mirror housing slipping
Sent:	Monday, October 25, 2010 13:09:27
From:	Glen Perry Jr. (
I have an ETX 90 RA. The shroud around the secondary appears to be
slipping to the left. It appears the glue or what ever adhesive used is
loosing its integrity. There is about one eighth of an inch crescent of
the shroud visible just to the right of the silver dot on the corrector
plate. Should I attempt to fix it or can you recommend someone that
could do the job? I called Meade and they did not wish to fix it but
offered a new OTA at a price that was high enough that I might as well
buy a new scope. The person at Mead's customer service suggested that if
i didn't wish to by a new OTA, that I remove the secondary cover and
replace it with super glue!
Mike here: If you want to attempt the repair yourself, see the articles "ETX-90RA Secondary Baffle Fix" and "Re-attaching the Baffle" on the Helpful Information: Telescope Tech Tips page. If you don't want to try it, Dr. Clay Sherrod may be able to fix it as part of his Supercharge Tune-Up Service (link on the Telescope Tech Tips page).


Thank you for your prompt reply. I will read the articles and let you
